Antagonistic hormones in plants

About this Research Topic. This Research Topic addresses the functional interactions between the signaling pathways controlled by two plant hormones: Abscisic Acid (ABA) and Gibberellins (GAs). Phytohormones play a crucial role throughout plant life cycle, as they control plant development and response to environmental changes.In the presence of two different hormones, the effects may be promotive, synergistic or antagonistic where one may modify the activity of the other. Such reactions are referred to as Hormonal interplay. Plant hormones play a major role in plant growth and development. antagonistic hormones in plants

Jun 23, 2010 Plant growth hormones: Antagonists cooperate. On the periphery of the tip, auxin triggers cells to leave the pool of stem cells, differentiate and form organs like leaves and buds. Cytokinin stimulates stem cells to divide and proliferate; it maintains the number of cells and thus the plant's growth potential.

Nov 29, 2012 AuxinCytokinin Antagonism Is Important Both for Development and Immunity. However, growthpromoting hormones (auxin, cytokinins, gibberellic acid, and abscisic acid) either inhibit or potentiate this balance in mediating the protection or susceptibility of the plant against the invading pathogen [10, [11. Aug 22, 2016 As an example of the antagonist's hormone, can take adrenaline and norepinephrine. Adrenaline excites the nervous system, increases blood pressure, and norepinephrineon the contrary.antagonistic hormones in plants Plant hormones act partially synergistic, partially antagonistic The number of different plant hormones is rather small when compared to animals. Many animal hormones, especially the macromolecular ones have a very limited action spectrum that has its root in the selectivity and the cellspecific or tissuespecific distribution of the respective receptors.

The hormones, which act against functions of each other, are called antagonistic hormones. In plants the cell division is controlled by the two main hormones, auxin and cytokinins. The auxins, like indole acetic acid (IAA) and cytokinins both promote the cell division, but the variation in the concentration results changes in cell division. antagonistic hormones in plants Antagonistic Hormones. When conditions exceed the upper limit of homeostasis, a specific action, usually the production of a hormone, is triggered. When conditions return to normal, hormone production is discontinued. If conditions exceed the lower limit of homeostasis, a different action, usually the production of a second hormone, is triggered. Hormones that act to return body conditions to within acceptable limits from opposite extremes are called antagonistic hormones. The two glands most responsible for homeostasis are the thyroid and the parathyroid.
